In a Work center hierarchy can i assign a person to multiple WCenters?

Is it possible to assign a pernr to two or more work centers in a work center hierarchy?

The requirement is we have a maintenance shared service ( which can be taken as main work center) and that do services for several work centers ( can be taken as child work centers) . So the people in main work center do the work in child work centers as well. they should be able to see the work orders created for them under those different work centers. it has to be HR integrated.
